Hello, I recently decided that I would like to have fresh eggs, so I bought a Red Barn coop, and a 5x10 run used online, and found a guy selling 6, 1 yr old laying Salmon Faverolles. I went to TSC and got Layer feed, and had a 1 gallon water feeder. The guy brought the chickens to me at about 1pm in the afternoon, and temps in the low/mid 90's. I installed a tarp over the 5x10 run, as the seller said that would help them with the heat. He put the chickens in the coop, I filled their feeders, and their water, and all seemed well. I came back to check on the chickens around 9pm, and top off their water feeder, because the seller said that a 1 gallon waterer wont last more than a day. They seemed to be alive and well at 9, and had one egg laying in the run. Topped their water off and went home. Around 1pm the next day, I brought them out a 5 gallon waterer, to find all the chickens dead. The waterer was still 2/3rds full, so I think they died in the middle of the night. There were a few of the small down white feathers in the cage, but no other signs of predators, no blood or injuries. 2 were up in the nesting box, and 4 were laying on the ground in the run. all had wings tight to their bodies, and heads curled under their wing. I have been in contact with the seller, and he is completely stumped as to what could have happened to the birds. The seller offered to replace them with some younger chickens, but we both would like to figure out what happened to these ones, before killing off anymore of them! The water is rural water, and I used a mid priced layer feed, so I don't know how in the world they could have ALL died at the same time. Could the heat/stress of being moved done it? I cant find anything that would of poisoned them. The land they are on has been vacant for years, and all Ive done on it since purchasing was mowed. I haven't sprayed with anything. Please help if you can, I am really disappointed wasting that much money on the chickens and supplies to only have chickens for 1 day! Thank you for any help you can offer.
